      Server Description

      A high-density, bare-metal ARM64 platform delivering massive DDR5 memory bandwidth and 192 dedicated physical cores for parallel, memory-intensive enterprise workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r8g.metal-48xl is a bare-metal, memory-optimized server featuring 192 dedicated physical ARM64 cores powered by the AWS Neoverse-V2 processor at 2.7 GHz. Equipped with 1536.0 GB of DDR5 memory, it provides 8.0 GB of RAM per core, though it lacks local storage and GPU accelerators. The server delivers top-tier multi-core CPU and memory bandwidth performance, as demonstrated by a stress-ng multi-core score of 291,012.56 and a Redis SET throughput of 357.86 million operations per second. While single-core speeds and LLM text generation represent performance tradeoffs, its massive memory capacity and high parallel processing capability offer excellent qualitative cost efficiency for memory-bound workloads. It is highly suited for large-scale in-memory databases, high-throughput web serving, and intensive software compilation.

      Workload Profiles

      9.57Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
